Sorry to say "pretend" implies a deciet or a lie, or a effort to defraud..

As I pointed out that I too have heard no screws effect and thus feel  that by impication I could be being slandered in the same way ... I have no connection with NVA other than to have heard their amps many moons ago. I also have no problems with robs opinions... but not ascertions that others sincerly held beliefs are wrong, which by implication includes mine.  

I'm certain a simple sorry from rob would close the gap, he can even say he thinks were wrong in his opinion......
